Optoma HD20 Projector problems

[jebarton3]

Hi so my projector works sometimes but sometimes it will just turn to blue screen and won't work. Sometimes it will startup and the blue screen will just be there. Again, sometimes it will work then it will blue screen and I will get weird colored horizontal lines. And then sometimes I will get the gray static screen... This is very frustrating because I can't seem to get it to work and stay working properly. Does anyone have any suggestions on how I can fix this problem?

First thing to check would be faulty HDMI port/cable.
Try using Component inputs or other inputs.
